gibson sg

just wondering, is the Gibson SG symmetrical? if my left handed friend buy it, change the order of the strings and the pickups upside down will it be the same?(not worrying about volume knobs, input and switch)

They are for the most part, (besides obviously the pickguard and controls) but yes the top horn is slightly longer, but not in any noticeable way when playing, they're very good for converting because you don't have to do any physical modifications besides changing the strings (and switching the nut, although this isn't absolutely necessary), the strap buttons can stay in the same place.
